DEME Offshore awarded EPC for Dogger Bank A and Dogger Bank B wind projects

DEME Offshore has been awarded a substantial engineering, procurement, construction and installation (EPCI) contract for the inter-array cables at the Dogger Bank A and Dogger Bank B wind farms in the UK, the first two phases of the 3.6 GW Dogger Bank Wind Farm which is the world’s biggest offshore wind farm under development.

The far-reaching scope includes the engineering, procurement, construction, and installation of the subsea cables for the combined 2.4 GW wind farm.  DEME Offshore will supply, install, and protect 650 km of 66 kV inter-array cables and all related accessories.

Dogger Bank Wind Farm is located more than 130km off the North East coast of England and is currently being developed in three 1.2 GW phases by joint venture partners SSE Renewables and Equinor. Dogger Bank will be the world’s largest offshore wind farm when complete and will generate enough energy to power over 4.5 million homes every year – around 5% of the UK’s electricity needs.

Production of the cable for Dogger Bank A and Dogger Bank B will start in 2021 and will be installed using our state-of-the-art DP3 cable installation vessel ‘Living Stone’.  The vessel has a huge cable capacity of more than 10,000 tonnes and a DEME-designed dual-lane system, consisting of two cable highways – one for laying the cable and one where the next cable can be simultaneously prepared and have the cable protection system (CPS) installed. This significantly reduces the time needed for preparing the cables, minimizes manual handling, increases the vessel’s workability, and ultimately, improves production rates.

DEME Offshore will work closely with SSE Renewables and Equinor to engage with the UK supply chain in the delivery of the project.
